Very cool little demo. The assets and gameplay are quite polished. Even though I beat the demo I still feel I didn't quite understand the frequency combat, but overall a solid entry to the jam and can definitely see the demo being expanded upon.
I think what initially confused me about that is the colors. Red is closer to the target frequency, right? Initially I assumed green before noticing the actual number. Maybe using an effect other than a color would work better?
Correct, Red is closer to the target frequency. I assumed that looking at your frequency and the enemies frequency would help make it clear that getting in the red make the shot deal more damage. Maybe should of clue that in the Game Tip.
